	</p>

		<div class="section"><h2 class="title sectiontitle">Enhancements and fixes</h2>
			
			<ul class="ul">
			<li class="li">The snapshot comparison queries have been enhanced to properly
			compare trees as well as tables.
			Also, a leak suspect report can be run on two snapshots to show possible memory leaks
			using the difference between the two snapshots of the memory usage of objects and components.</li>

			<li class="li">Memory Analyzer now has a configuration option to allow an attempt to analyse
			huge heap dumps, bigger than Memory Analyzer could handle in previous version. It does this
			by optionally discarding some objects from the heap dump while building the snapshot, with
			the hope that the important objects have not been discarded.</li>

			<li class="li">Stand-alone Eclipse Memory Analyzer is now based on Eclipse 2020-03 which
			may give a slightly improved user interface compared to previous versions.
			As a consequence, stand-alone Eclipse Memory Analyzer is only available for
			the following platforms.
				<ul class="ul">
					<li class="li">Windows (x86_64)</li>

					<li class="li">Mac OS X (Mac/Cocoa x86_64)</li>

					<li class="li">Linux (x86_64/GTK+)</li>

					<li class="li">Linux (PPC64LE/GTK+)</li>

				</ul>

			The macOS build is now signed and notarized.
			</li>

		<div class="section"><h2 class="title sectiontitle">Security fixes</h2>
			
			Memory Analyzer 1.11 includes the security fixes first included in Memory Analyzer 1.9.2.
			We highly recommend users of Eclipse Memory Analyzer version 1.9.1 or earlier to update to version 1.11.0 (or 1.10.0 or 1.9.2) or subsequent versions.

					<dt class="dt dlterm"><a class="xref" href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-17634" target="_blank">CVE-2019-17634</a></dt>

						<dd class="dd"><dl class="dl">
							
								<dt class="dt dlterm">PROBLEMTYPE</dt>

								<dd class="dd">CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')</dd>

							
							
								<dt class="dt dlterm">DESCRIPTION</dt>

								<dd class="dd">Eclipse Memory Analyzer version 1.9.1 and earlier is subject to a cross site scripting (XSS) vulnerability when generating an HTML report from a malicious heap dump. The user must chose to download, open the malicious heap dump and generate an HTML report for the problem to occur. The heap dump could be specially crafted, or could come from a crafted application or from an application processing malicious data. The vulnerability is present when a report is generated and opened from the Memory Analyzer graphical user interface, or when a report generated in batch mode is then opened in Memory Analyzer or by a web browser. The vulnerability could possibly allow code execution on the local system when the report is opened in Memory Analyzer.</dd>

						<dd class="dd"><dl class="dl">
							
								<dt class="dt dlterm">PROBLEMTYPE</dt>

								<dd class="dd">CWE-502: Deserialization of Untrusted Data</dd>

							
							
								<dt class="dt dlterm">DESCRIPTION</dt>

								<dd class="dd">Eclipse Memory Analyzer version 1.9.1 and earlier is subject to a deserialization vulnerability if an index file of a parsed heap dump is replaced by a malicious version and the heap dump is reopened in Memory Analyzer. The user must chose to reopen an already parsed heap dump with an untrusted index for the problem to occur. The problem can be averted if the index files from an untrusted source are deleted and the heap dump is opened and reparsed. Also some local configuration data is subject to a deserialization vulnerability if the local data were to be replaced with a malicious version. This can be averted if the local configuration data stored on the file system cannot be changed by an attacker. The vulnerability could possibly allow code execution on the local system.</dd>
